SELF-DUMPING-VEHICLE. 1

'A pplication filed December 3,1920. sen-a m. 423,112.-

To all whom it may concern. I

Be it known that 1, Fnrrz FrNoKH, residing at Essen, Germany, acitizen of the German Republic, have invented a certain new and useful Improvement in Self-Dumping Vehicles, of which the following is a specification.

This invention relates to self-discharging vehicles discharging, from the bottom, and has for its special object, by establishing a joint connection between the bottom doors which are adapted to be automatically opened by the weight of the lading and the outer walls, which serve to confine the loading space and immediately adjoin the respective outer end portions of said doors, to cause these outerwalls to move conjointly with the doors and thereby to secure a breaking up of the lading, further the quick formation of steep chutes, and lastly the provision of a large discharge opening.

One embodiment of the subject matter of my invention is illustrated in the accom panying drawing, showing a railway selfdumping vehicle which the axes of rotation of the bottom doors are disposed in the longitudinal direction of the vehicle.

Fig. 1 is a cross sectional view of the selfdumping vehicle ready for loading, and

Fig. 2 a similar view showing the vehicle in the discharged'state.

The two bottom doors B are connected, so as to allow of swingin motion, with respect to the stationary under frame A of the vehicle by means of bearings a? disposed to either side of the central longitudinal plane. The said doors are arranged at an incline, their lower edges bearing against each other in the central longitudinal plane of the vehicle, they thus meeting to form a funnelshaped loading space, while their upper edges are provided with bearings 6 by means of which they are pivotally connected with the side members or walls C of the vehicle. ulated at the ends of its upper edge, facing the stationary end walls A of the vehicle, by means of a hinge c with the end of a guide link D adapted to rotate about a pivot a fixed in the said end wall A When the vehicle is ready for loading, the two bottom doors B are interconnected at their lower edges 6 by intervention of any convenient simple locking device one embodi- Each of these latter is in turn articment of which isshowninjthe drawing. It comprises the latch e pivoted atdto one of the doors B and adapted to engage a pin f rigidly fixed on the opposing door.

. The bearingsu aredisposed relativelyvto theb ottom doors B suchwise that when the vehicle is ,loaded and theflockingdevice released, the bottom doors will automatically open outward, in consequence of the effect exerted by the weight of the load. I

It will thus be readily understood that when the vehicle is to be discharged of its contents, the locking device, which secures the bottom doors, is first of all released, whereupon these doors being opened downwards by the weight of the lading by rotating around the axes of bearings a the said doors lifting at the same time the side walls C which are articulated to their upper edges, and causing said side walls to swing inwardly in the direction indicated by the arrows 00 in Fi 1, the walls assuming then the position Si causes a large discharge openin to be ter and said side walls now being disposed own in Fig. 2. This position in practically one and the same plane, that is, in approximate parallelism, which again yields a steep chute, so that lading materials possessing even a great power ofcohesion and adhesion may be reliably and quickly discharged. The discharging operation is moreover additionally facilitated by the fact that, owing to the sudden change in the configuration of the cross sectional area of the vehicle, the material to be discharged is suitably broken up and loosened.

The discharge having been effected, the movable parts of the vehicle. automatically return into the initial position as shown in Fig. 1, and this occurs either and solely by the effect of their own proper weight, or else by the intervention of spring means or counter weights, whereupon the bottom doors are once more interconnected at b by means of the'locking device.

I claim:

1. In an automatic self-dumping vehicle, a bottom portion comprising two doors swingingly mounted on the vehicle frame side Walls is swung into approximate parallelism with its connected door in the-course V 2. In an aiitomatio self dumping vehicle, I a bottom portion comprising doors swingingly mounted on the vehlcleyframe and;

adapted to open centrally and automatically. by the, Wei ht of e n n tion ry d walls; and side Walls artioillated at their lower edges to the said doors and connectedattheir upp er edges to gnide links rotatably mountedpn'the, said :end Walls.

3; In anautomatic self dnmping vehicle, a bottom portion comprising doors swingingly mounted on the vehicle frame and adapted to open centrally and automatically by the Weight ofthe lading stationary end Walls, and; side. Walls articulated at their lower edgesto th'e said doors and oonnected at their upper edges tognide links rotata-bly FRITZ FINOKH.
